Maintenance and storage of axial fans

The operating environment should be kept clean and tidy at all times, the surface of the fan should be kept clean, there should be no debris at the air inlet and outlet, and the dust and other debris in the fan and pipeline should be cleaned regularly . The fan can only be operated under normal conditions. At the same time, it is necessary to ensure that the power supply facilities have sufficient capacity and stable voltage. Defective operation is strictly prohibited. The power supply line must be a dedicated line and should not be used for long-term temporary power supply. During the operation of the fan, it is found that the fan has abnormal sound, the motor is severely heated, the shell is electrified, the switch is tripped, and it cannot be started. It should be shut down immediately for inspection. In order to ensure safety, maintenance is not allowed during the operation of the fan. After the maintenance, a test run should be carried out for about five minutes to confirm that the re is no abnormal phenomenon before starting the operation. Replenish or replace the lubricating grease on the bearing irregularly according to the use environment conditions (the motor closed bearing does not need to replace the lubricating grease during the service life). In order to ensure the good lubrication of the fan during operation, the number of refueling shall not be less than 1000 hours/time. For bearings and motor bearings, fill 1/3 of the inner and outer rings of the bearing with zl-3 lithium base lubricating grease; it is strictly forbidden to run out of oil. The fan should be stored in a dry environment to prevent the motor from getting damp. When the fan is stored in the open air, there should be defensive measures. During storage and handling, the fan should be prevented from bumping to avoid damage to the fan.
